I'm in my ninth day of a ten day regimen of Levaquin for treatment of a sinus infection. I suppose I have fared better than most on this board. I Googled Levaquin and ringing ears due to a recent onset of that symptom. I have also had a mild, nagging headache at the base of my skull or upper neck. I have also experienced a slight queasiness in the past two days, but nothing close to nausea. The past three nights, I have had unusually vivid dreams, although I don't recall any of them being what I would describe as nightmares. Finally, in the past two days, I have experienced what I can only describe as deja vu kind of feelings throughout the day. My symptoms have increased somewhat during the past several days, but none could be described as severe. I guess I will take my final dose and hope for the best, but I will probably try to avoid this drug in the future.
